Abstract

In work are considered problems of diffraction of electromagnetic waves by the impedance convex cylinder for two cases : the observation point and source point are located on removal from the cylinder and a source point is located in the close vicinity of the convex cilinder. Process of obtaining asymptotic interpolation formulas, suitable for calculations both in shadow and in lighted zones is described.
